Querying Solr from XMLUI

Since Solr returns its responses in XML, it's possible and easy to call custom Solr queries from XMLUI, process the XML response with XSLT and display the results in human-readable form on the HTML page.
There are two ways how to do that - synchronously in Cocoon or asynchronously using AJAX (JavaScript) after the page is loaded. Solr queries are usually very fast, so only synchronous calls will be shown here.

You can include another XML document to be processed by XSLT using the document() function. The parameter to this function is an a string with the path to the XML document to process. This can be either a static .xml file stored on the server filesystem or a URL, which will be fetched at time of processing. For Solr, the latter is what we need. Furthermore, we need to distinguish templates for processing this external XML document as opposed to the input XML document. We'll do this using the mode attribute and define a different processing mode for each query.

<xsl:apply-templates select="document('http://localhost:8080/select?q=search.resourcetype:2&amp;sort=dc.date.accessioned_dt%20desc&amp;rows=1&amp;fl=dc.date.accessioned_dt&amp;omitHeader=true'))"
mode="solr-response"/>
